WILSON POLK HARLAN, OF, HOLTVILLE. CALIFORNIA.

FLUME-GAT E.

To all whom it may concern:

Be it known that I, W'rLsoN P. HARLAN, a citizen of the United States, residing at Holtville, in the county of Imperial and State of California, have invented certain new and useful Improvements in Flume- Gates, of which the following is a specification.

The present invention relatesto those devices commonly known as flume gates.

An important object 'of my invention is to provide a flume gate of simple and compact structure, which will be strong, durable, and will not leak.

A further object of the invention is to provide a device of the above mentioned character, which may be quickly and easily put in its operative position and which Wlll be easy to operate therein.

A further object of the invention is to improve the construction in general of these devices and to provide a flume gate which is highly proficient in fulfilling its function.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which. like numerals are employed to designate like parts throughout the same, Figure 1 is a front elevation of the flume gate, Fig. 2 'is a vertical sectional view taken on line 22 of Fig. 1, Fig. 3 is a horizontal sectional view taken on line 3 3 of Fig-1, Fig. 4 is a similar view taken on line 4-4- of Fig. l. and, Fig. 5 is a fragmentary front elevation of the upper portion of a plate forming the body portion of the flume gate.

In the drawings wherein is illustrated a preferred embodiment of my invention, the numeral 1 designates a strand pipe. preferably formed of concrete or the like, for rereceiving a tube or flume 2, provided at its outer end with an outwardly extending annular flange 3. I

The numeral 4 designates thebody portion of the flume gate and is in the form of a .plate provided with a central opening 5, for receiving the flume 2, as shown. The flange 23 engages upon the outer face of the plate 4 and irgl'ds the same in firm engagemeiyt with thestrand pipe 1. .\t its lower end the plate 4 extends below pipe 1 and is bent upwardly for-forming a curved receiving flange 6. as shown. The flange (3 is provided with openings (3, for a purpose to be Specification 6r Letters Patent.

otherwise rigidly secured to the open frame.

The plate 4 isbent at its vertical edges, forming vertical curved receiving flanges 10, which are also disposed within the open frame 7. The forward walls of these curved flanges are provided with upwardly extending flaps 11, which are bent forwardly and downwardly about the forward side 12 of the open frame "1', and may be soldered or otherwise rigidly secured thereto. The forward walls of the vertical receiving flanges 10 preferably terminate at points above and spaced from the horizontal receiving flange 6.

-The numeral 13 designates a slide plate adapted for operation through the frame 7 and in the receiving flanges 10 and 6. At-

tention is called to the fact that the plate 4 and the receiving flanges are formed of sheet metal and accordingly yieldingly hold the slide plate. in firm engagement with the flange 3 of the flume 2. The slide plate 13 has a tongue 14 stamped from the upper portion of its material and bent to form a handle or other means by which the slide plate may be moved. The forward side 12 of the open frame 7 is provided with an inwardly extending clamping tongue 15, extending between the flanges l0 and engaging the slide plate 13 to hold the same in proper engagement with the flange 3.

in. the use of. my improved flume gate material may be discharged through the flume 2 by raising the slide plate 13. The ol'ienings (3 in the lower receiving flange 6 preventjhe accumulation of mud or the like in the flange (3.

It is obvious that the flume gate as a whole is of simple construction, is strong, durable, and will not leak.

I wish it understood that the form'of my invention herewith shown and described is to be taken as a preferred example of the same and that certain changes in the shape,

thus described myinvention I claim 1. The combination witha flume, of a plate provided with an'opening and connected with said flume, said plate being providedwith receiving flanges, an open frame connected with the upper end of the plate and with the receiving flanges, and a slide plate operatin through the open frame and the receiving anges,

. 2. The combination with a flume, of a plate having an opening formed therethrough and connected'with said flume, said plate being provided with vertical receiving flanges, an open frame receiving the plate andthe flanges and connected with the same, a slide plate operating through the open frame and the receiving flanges, and an inwardly extending clamping, tongue formed upon the forward side of the open frame I and engaging the slide plate.

3. The combination with a flume, provided at its discharge end with an outwardly extending flange, of a plate having-an opening for receiving the flume and to be en gaged by the outwardly extending flange,

said late being provided with spaced vertical receiving flanges. and a'lower horizontal receiving flange having openings formed 'therethrough to prevent the accumulation of ,mud or the like, and aslide plate for'opera i tion within said receiving flanges."

4. The combination wlth :i flume, having at its discharge end an outwardly extending flange, of a plate provided with an opening for receiving the-flume, and to be engaged by theoutwardly extending flange, said plate being provided with upstanding receiving flanges, an'open frame receiving the plate and flanges, said plate and flan es having flaps bent about the open frame or forming suitable connection between the same, and a slide receiving flanges.
